DUSTING MOP `Application led February 6, 1929. Serial No. 337,867.

This invention relates to improvements in dusting mops and particularlyto that type of such mops in which a loop shaped metallic frame carriesthe mop material.

It is the object of the present invention to provide a mop` frame whichforms a closed loop covered by a sheath of fabric having mop cords whichform a heavy fringe thereon and means Vfor quick attachment ofsaid 19sheath to its frame or removal therefrom.

Itis another object of the invention to provide a mop frame which holdsand clamps the mop sheath so that it cannot be accidentally removed fromthe frame. i It is a further object of this invention to provide alooped mop frame which yields .resiliently on its forward stroke whenstriking a solidl object or by friction against the surface which isbeing cleaned.

Vith these and other objects in view which will become clearer as thedescription progresses, the invention consists in a novel constructionand combination of parts hereini u after more fully described andfinally pointi' 20 ed out in the appended claims.

In the drawings which form a material part of this disclosure:

Fig. 1 is a perspective frontelevation of a mop embodying the inventionshowing two separate sheaths partly assembled on the frame. y

y Fig. 2 illustrates the mop of Fig. 1 when completely assembled.

Fig. 3 shows the mop frame illustrated in Figs. 1 and 2 during theapplication of a single mop sheath to both arms of the frame. Fig. 4shows the mop of Fig. 3 completely assembled. `-Fig.5 is a diagrammaticillustration of a '1Q y looped mop frame having `overlapping arms in itsrearward portion.`

Fig. 6 is a diagrammatic illustration showing the invention applied to amop frame of triangular shape.

Fig. 7 is an enlarged detail elevation of the resilient 4connector whichjoins the mop frame arms to the mop stick partly in section on line 7--7of Fig. 1.

Fig. 8 is a side elevation of Fig. 7 partly .CJ in Section on line 8-8of that figure.

Referring to the drawings, 10 is a helical l coil of wire, having anopen wound portion 10a and a closely wound portion 10b of smaller`diameter. Portion 10a forms a threaded socket for aniop stick 13 thebottom of which leans against the first turn of 10b which forms a stoptherefor. The coil portion 10b holds the ends of two metallic bars 11lying fiat against each other. The end portions areshaped as shown inFig. 7 havin a taper portion 11a, a wide portion 11c an a narrow portion11". Outside of coil `10 each bar 11 is bent to form a U shapedresilient arm bent in opposite direction to `the other bar as shown inFig. 3. of bars 11 overlap each other fora `distance and their fiatsides leanagainsteach other, end portion 11d pressing inwardly againstend portion llcrwhich presses in outward direction. In this manner acontinuous loop is formed by the two arms without any open spacetherein. i

The mop material 14: is bound in by tubular fabric sheaths 15 which areslipped upon each one of the arm-ends 11d and 11e. A separate sheath 15may be used for each arm as illustrated in Figs. 1 and 2 or a singlesheath of double length as shown in Figs. 3 and 4. For applying thedouble sheaths to a mop frame, ends 111 and 11e are pressed apart byhand and a sheath 15 threaded over the free end of each arm 11 so far,that the overlapping end portions remain uncovered as shown in Fig. 1.The ends are then released to snap against each other and the sheathsare stretched over the overlappin arm portions to cover them as shown inig. 2.

` A single` sheath for covering both arms is applied to the mop `frameas shown in Fig. 3 by threading one of its open ends on each arm andallowing an empty middle portion of` the `sheath to lie between the flatinner faces of 11.d and 11E forming a reverse bend and clamping ittightly between said ends as shown in Fig. 4.

\ The fastening of the two frame arms 11 to coil 10 is a modication ofmy invention shown and described in my application for Letters Patententitled Holder for dusters and the like Ser. No. 275,985 filed May 8th,
